Abstract
An in vitro method for screening Glycine max cells for resistance to a disease caused by Phialophora gregata, brown stem rot, is disclosed. The method is useful for identifying brown stem rot resistant soybean varieties. Means for selecting mutant soybean cells for resistance to a toxin produced by P. gregata is also provided, as are cells and plants selected by this process. The invention involves culture of soybean calli in the presence of a filtrate of used fungal growth medium.
